Photo Tour Of Facebook’s New Datacenter

Scobleizer
Today I was very fortunate to have gotten a tour of Facebook's new datacenter up in Prineville, Oregon (map). This datacenter is the most energy efficient in the world and only a handful of press got a look. We'll have a video up after editing it, but here's a look at the datacenter in photos. I shot all of these photos on an unmodified iPhone 4 with Instagram, that just got an update today. For the panoramic photos I was using Occipital's 360 app.

Here’s the sight that we saw on arriving

Keep in mind this building is HUGE and there's a sizable solar array out front (here's a panoramic photo from inside that solar array), which doesn't really power much of the datacenter, but powers some of the buildings around the site. Photos don't really do it justice, but think about three average Walmarts put end-to-end.

Facebook is so big that it has its own flag

Walking in, yes, we are in the right place:

Just past the Facebook sign is a monitor in the lobby that shows you the state of the datacenter and how well the cooling systems are working

Inside the security door the local community made these quilts, which is their interpretation of what a social network looks like

Walking in Thomas Furlong, director of site operations at Facebook, brought us into a huge series of rooms which “process” the air.

First room filters the air. Second room filters it further.

Here's Thomas showing us one of the huge walls of filters (these filters are similar to the ones in my home heating system, except here Facebook has a wall of them).

Here’s a better shot of just how massive this filtering room is

Then the air goes into a third room, one where the air is mixed to control humidity and temperature (if it's cold outside, as it was today, they bring some heat up from inside the datacenter and mix it here) and on the other side, there's a huge array of fans, each of which has a five horsepower motor (today the fans were moving at 1/3 speed, which makes them more efficient)

Here you can see the back sides of one of the huge banks of filters

Here’s a closeup look at one of the fans that forces air through the datacenter and through the filtering/processing rooms

Finally, the air moves through one final step before going downstairs into the datacenter

In this final step small jets spray micro-packets of water into the air. As the water evaporates, which it does very rapidly, it cools the air. One room I didn't take photos in was filled with pumps and reverse osmosis filters, which makes the water super pure so it works better when using it to cool in this way. One final set of filters makes sure no water gets into the datacenter. Here's a closer look at the array of water jets.

Here you can see the scale of the room that sprays that water

Finally we got to follow the air down into the datacenter where there was a huge floor with dozens of rows. Each row had rack after rack of servers. Here Thomas stands in front of just one of those racks

This is a 180-degree view of the main corridor

This 180-degree view gives you a look down the main corridor (on the side you can see is only half the datacenter — these are the newer "Open Compute" servers, the other half they asked us not to take pictures of, and that contained their older server technology).

Which brought up the question: why Prineville?

The execs who showed me around today said they chose the site based on an exhaustive search for the perfect combination of low-seismic risks, cooler and mostly dry weather, access to power and Internet trunk lines (Prineville is an old railroad community, and fiber lines run under the railroads here) and a variety of other factors including low tax rates and friendly climate to business, etc.

Anyway, it's not often that you get to see inside a modern datacenter. You'll be reading more about this tour, since there were other journalists there as well, hope you enjoyed these early pictures.

By the way, why did Rackspace send me there? For those who don't know, I'm a full-time employee of Rackspace which is the world's biggest web hosting company.

Because we're already building a datacenter based on the "Open Compute" plans that Facebook made and put into Open Source (the datacenter as well as the specs for the machines is all in open source now). More on Open Compute here. Plus we're datacenter geeks so love seeing how other companies do it so we can learn from what they've done.
